Description

Technical Field

[0001] The utility model relates to the technical field of rubber product processing, and more specifically to a numerically controlled lathe for efficiently turning rubber sealing parts. Background Art

[0002] Rubber seals are round rubber products, generally used for leak prevention, and have the physical properties of natural rubber. Rubber seals are often used in different places, and they include a round hole. In the existing preparation process, CNC punching is commonly used after injection molding. In this punching method, the tool contact surface of the round hole and the punching marks on the other side are different, because the tool contact surface of the round hole is stamped and cut, while the surface on the other side is actually torn. This is not allowed for the production of rubber seals with tolerance requirements on both sides, which seriously affects the product quality of the rubber seals.

[0003] After searching, the document with publication number CN115319842A discloses a CNC cutting tool for non-destructive circular holes of rubber seals. By setting an arc-shaped blade, when cutting circular holes in rubber seals, the contact area between the arc-shaped blade and the rubber seal is small, thereby generating less heat, avoiding the situation where the rubber softens and melts, resulting in blade breakage and deformation in the product hole, thereby improving product quality and work efficiency.

[0004] When the above-mentioned prior art is actually used in conjunction with a lathe, the rubber seal has a certain temperature after injection molding. Even if it is cut after cooling, the cutter will generate heat due to friction after a long period of cutting. Whether it is the heat of the rubber seal itself or the heat generated by friction, the heat will eventually be transferred to the blade, causing the blade to heat up and adhere to more cutting residues. When there are too many rubber residues adhered to the surface of the blade, it will have an adverse effect on subsequent cutting. Utility Model Content

[0045] The working principle and use process of this utility model:

[0046] First, the rubber seal to be processed is placed on the vehicle body 100 and fixed. According to the required cutting size, the adjusting screw 403 is rotated to make the moving block 404 drive the cutter 405 to move, and the position of the cutter 405 is adjusted to meet the cutting requirements;

[0047] Then, the servo motor 301 drives the lifting screw 302 to rotate, so that the lifting platform 303 drives the cutter 405 to move downward, and the stepping motor 401 drives the adjustment box 603 to rotate the cutter 405 for processing;

[0048] After the cutting is completed, the servo motor 301 drives the lifting screw 302 to reverse, so that the lifting platform 303 drives the cutter 405 to move upward. During the upward movement of the lifting platform 303, the steering member 505 is driven by the rotating shaft 502 to gradually move out from the lower half of the through slot 506. When the steering member 505 moves to the critical point of the lower half of the through slot 506, the gear 503 and the rack 504 are docked. As the rise continues, the gear 503 and the rack 504 cooperate to make the gear 503 rotate. After the gear 503 rotates 180°, the rotating shaft 502 drives the cutting mechanism 400 to rotate 180°, so that the cutter 405 faces upward. The gear 503 and the rack 504 reach the critical point of separation. At this time, the steering member 505 moves to the critical point of the upper half of the through slot 506. Then, when the gear 503 and the rack 504 are separated, the steering member 505 enters the upper half of the through slot 506.

[0049] Afterwards, the cutting mechanism 400 rotates 180°, and the cutter 405 faces upward and continues to move upward. When it can enter between the two adjustment boxes 603, it is cleaned by the cleaning wiper 604, and the circulating pump 606 pumps out the coolant in the cooling water tank 605, and returns to the cooling water tank 605 after passing through the telescopic bellows 608, the heat exchange tube 607 and another telescopic bellows 608. When the coolant passes through the heat exchange tube 607, it exchanges heat with the adjustment box 603, so that the temperature of the adjustment box 603 drops to cool the cutter 405.

[0050] In summary, in the present invention, after cutting the rubber seal, the cutter 405 is reversed, and the cutter 405 is cleaned and cooled, which effectively prevents the cutter 405 from adhering to residues, and also prevents the cutter 405 from heating up and easily adhering to cutting residues, thereby reducing the adverse effects on subsequent cutting;

[0051] Among them, in the present invention, the PLC controller 101 is programmed accordingly to control all electronic components, and the adjusting screw 403 and the transverse screw 602 can use corresponding motors as power sources to achieve automatic control.

[0052] The electronic components and modules used in the content of this utility model can all be parts that are commonly used in the market and can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs. The electronic components and modules are all connected to an external power supply and a control switch for use.
